MACOM Technology Solutions Holdings is rated Hold as its forward EV/EBITDA of 46x sits 58 percent above its five-year average despite strong operational execution. My probability-weighted valuation is $272.83 per share, 9.6 percent below the current price, with scenarios ranging from $155.86 in the bear case to $383.95 in the bull case. Strong Q3 growth is offset by rising Customer A and China revenue concentration alongside $340.5 million in now-current convertible notes.
